Vile Vortices is a term referring to twelve geographic areas that are alleged by Ivan Sanderson to have been the sites of mysterious disappearances. He identified them in a 1972 article "The Twelve Devil's Graveyards Around the World", published in Saga magazine. 
Sanderson asserts that twelve "vortices" are situated along particular lines of latitude.
The best known of the so-called "vortices" is the Bermuda Triangle. Others include Algerian Megaliths to the south of Timbuktu, the Indus Valley in Pakistan, especially the city of Mohenjo Daro, Hamakulia Volcano in Hawaii, the "Devil's Sea" near Japan and the South Atlantic Anomaly. Five of the vortices are on the same latitude to the south of the equator; five are on the same latitude to the north. The other two are the north and south poles.
Paul Begg, in a series of articles for The Unexplained magazine, criticized the methodology of writers on the subject of unexplained disappearances. He checked original records of the alleged incidents. Often, he found, the ships which were claimed to have 'mysteriously disappeared' had a mundane reason for their loss (see for instance Raifuku Maru). Some were lost in storms, although the vortex writers would claim that the weather was fine at the time. In other cases, locations of losses were changed to fit the location of the vortex. Sometimes no record of the ship even existing in the first place was found.
